[ANNOUNCE] Weekly Community Update 2020/22

[Konstantin Knauf-4]

Dear community,

happy to share this week's community update with an update on the upcoming
Apache Flink releases: Flink 1.11 and Flink Stateful Functions 2.1. With
the community focused on release testing  the dev@ mailing list remains
relatively quiet.

Flink Development
==============

* [releases] Release Testing for Flink 1.11 is progressing. To follow the
testing efforts check out the Flink 1.11 burndown board [1] in the Flink
Jira. Stephan proposes to backport FLIP-126 to Flink 1.11 (after the
feature freeze) as it is an isolated change and to avoid breaking the newly
added source interface again in the next release. [2]

* [releases] Apache Flink-shaded 11.0 was released. Flink 1.11 will depend
on it. [3]

* [releases] Gordon just published the first release candidate for Apache
Flink Stateful Functions 2.1. [4]

* [savepoints] I started a small discussion about documenting (breaking)
backwards compatibility of Apache Flink's savepoint format. [5]
